Welcome to issue #193 of The Process, the newsletter for FlowingData members that looks closer at how the charts get made. I’m Nathan Yau, and this week I’m checking out the gridlines on charts. They serve as a point of reference in some charts and guide the eyes in others, coming in different styles and layouts. Become a member for access to this — plus tutorials, courses, and guides.
Named after the grid system Thomas Jefferson used to apportion land acquired through the Louisiana purchase, the Jefferson Grid Instagram account highlights remnants of the system through satellite shots from Google Earth. Each picture is the land that fits into one square mile. The most fun ones more me are the desert shots. It's a square mile of development and just dirt everywhere else. Tags: grid, Thomas Jefferson
